Harsh weather moved west on Monday as a polar vortex was expected to grip the Rockies and the northern Plains after winter storms pummeled the eastern US over the weekend, killing at least 10 people, including nine victims in Kentucky who died during flooding from heavy rains.

The National Weather Service warned of “life-threatening cold” into Tuesday, with temperatures in northeastern Montana predicted to dip as low as 45 degrees below zero (-42.7 degrees Celsius) with wind chills down to 60 below (-51 degrees Celsius).

Dangerously cold wind chill temperatures as low as 50 degrees below zero (minus 45.6) were expected in most of North Dakota, which remained under an “extreme cold warning” along with large swaths of South Dakota and Minnesota, according to the weather service.

Meteorologists said several states would experience the 10th and coldest polar vortex event this season. Weather forces in the Arctic are combining to push the chilly air that usually stays near the North Pole into the US and Europe.

Kentucky, Appalachia battered by flooding

Kentucky Gov. Andy Beshear announced Sunday that the death toll in his state had risen to nine and at least 1,000 people stranded by floods had to be rescued. President Donald Trump approved Kentucky's request for a disaster declaration, authorizing the Federal Emergency Management Agency to coordinate relief efforts throughout the state.

In Atlanta, a person was killed when a large tree fell on a home early Sunday, raising the overall death toll from harsh weather to 10.

Parts of Kentucky and Tennessee received up to 6 inches (15 centimeters) of rain, Bob Oravec, a senior forecaster with the National Weather Service, said Sunday.

Water submerged cars and buildings in Kentucky and mudslides blocked roads in Virginia over the weekend. Flood warnings extended throughout Tennessee and Arkansas.

In West Virginia, 13 southern counties were under a state of emergency for flooding and some areas were cut off to vehicle traffic Sunday. Several volunteer fire departments dealt with flooding in their own buildings while answering rescue and evacuation calls.

Rockies, Midwest, Northeast hit with snow storms

Ice and snow made road travel treacherous in large swaths of Michigan, which remained under a winter weather advisory until Monday afternoon. Michigan State Police reported 114 crashes Sunday around the Detroit area since snow started falling Saturday.

“Fortunately, most were one-car spin outs and there were no serious injuries,” Michigan State Police said on X.

Authorities in Colorado reported eight people were killed in fatal vehicle crashes since Valentine’s Day and warned drivers to be cautious as the weather made driving more difficult. The causes of the fatal crashes weren’t immediately known.

Also in Colorado, three state patrol cruisers that had pulled over along roadsides were struck by other vehicles, including one on Sunday where a trooper had stopped as officials prepared to close a road because of ice. In each case the troopers were out of their cruisers at the time and were uninjured.

Avalanche warnings were issued for numerous areas of the Rocky Mountains stretching from Colorado to Washington state, with the danger rated highest in Utah.

Part of Detroit is submerged in water after pipe burst

Parts of a southwest Detroit neighborhood are submerged after a nearly century-old water main burst early Monday.

The 54-inch (137-centimeter) transmission main was built in 1930 and has left several feet of water over streets, sidewalks and yards, according to the Great Lakes Water Authority.

Crews and contractors were in the area attempting to isolate the break. It was not clear what caused the main to burst, but temperatures late Sunday into Monday morning were well below zero degrees Fahrenheit (minus 17 degrees C).

No injuries have been reported. Firefighters used a ladder to help one person from the roof of a car in waist-deep water and a bulldozer was used to navigate a flooded street and help people leave a home, according to the fire department.

Mayor Mike Duggan says people impacted by the flooding can shelter in place if they have power and feel safe. Those who want to leave can call 911 and fire crews will help them from their homes and take them to a temporary shelter.

Avalanche warnings for Rockies and elsewhere

Avalanche warnings were issued for numerous areas of the Rocky Mountains stretching from Colorado to Washington state, with the danger rated highest in Utah.

The Mount Washington Avalanche Center issued an avalanche warning Monday for several places in the White Mountains — including Tuckerman Ravine, Gulf of Slides, Huntington Ravine, and Great Gulf — in the state of New Hampshire.

Two ice climbers were rescued in the White Mountains on Sunday after they triggered an avalanche and one of them became partially buried in the snow, the New Hampshire Fish and Game said in a statement.

NASA astronauts Butch Wilmore and Suni Williams returned to Earth in a SpaceX capsule on Tuesday with a soft splashdown off Florida's coast, nine months after their faulty Boeing Starliner craft upended what was to be a week-long stay on the International Space Station.
Their return caps a protracted space mission that was fraught with uncertainty and technical troubles, turning a rare instance of NASA's contingency planning - and the latest failures of Starliner - into a global and political spectacle, Reuters reported.
Wilmore and Williams, two veteran NASA astronauts and retired US Navy test pilots, had launched into space as Starliner's first crew in June for what was expected to be an eight-day test mission. But issues with Starliner's propulsion system led to cascading delays to their return home, culminating in a NASA decision to fold them into its crew rotation schedule and return them on a SpaceX craft this year.
On Tuesday morning, Wilmore and Williams strapped inside their Crew Dragon spacecraft along with two other astronauts and undocked from the ISS at 1.05 a.m. ET (0505 GMT) to embark on a 17-hour trip to Earth.
The four-person crew, formally part of NASA's Crew-9 astronaut rotation mission, plunged through Earth's atmosphere, using its heatshield and two sets of parachutes to slow its orbital speed of 17,000 mph (27,359 kph) to a soft 17 mph at splashdown, which occurred at 5:57 p.m. ET some 50 miles off Florida's Gulf Coast under clear skies.
"What a ride," NASA astronaut Nick Hague, the Crew-9 mission commander inside the Dragon capsule, told mission control moments after splashing down. "I see a capsule full of grins, ear to ear."
The astronauts will be flown on a NASA plane to their crew quarters at the space agency's Johnson Space Center in Houston for a few days of routine health checks before NASA flight surgeons say they can go home to their families.
"They will get some well-deserved time off, well-deserved time with their families," NASA's Commercial Crew Program chief Steve Stich told reporters after the splashdown. "It's been a long time for them."
POLITICAL SPECTACLE
The mission captured the attention of US President Donald Trump, who upon taking office in January called for a quicker return of Wilmore and Williams and alleged, without evidence, that former President Joe Biden "abandoned" them on the ISS for political reasons.
NASA acted on Trump's demand by moving Crew-9's replacement mission up sooner, the agency's ISS chief Joel Montalbano said Tuesday. The agency had swapped a delayed SpaceX capsule for one that would be ready sooner and sped through its methodical safety review process to heed the president's call.
Trump told Fox News on Tuesday that Wilmore and Williams will visit the Oval Office after they recover from their mission.
Wilmore earlier this month told reporters on a call from the ISS that he did not believe NASA's decision to keep them on the ISS until Crew-10's arrival had been affected by politics under the Biden administration.
SpaceX CEO Elon Musk, a close adviser to Trump, had echoed Trump's call for an earlier return, adding the Biden administration spurned a SpaceX offer to provide a dedicated Dragon rescue mission last year.
NASA officials have said the two astronauts had to remain on the ISS to maintain adequate staffing levels and it did not have the budget or the operational need to send a dedicated rescue spacecraft. Crew Dragon flights cost between $100 million to $150 million.
Crew Dragon is the only US spacecraft capable of flying people in orbit. Boeing had hoped Starliner would compete with the SpaceX capsule before the mission with Wilmore and Williams threw its development future into uncertainty.
Stich said on Tuesday that Starliner might need to fly another uncrewed flight - which would be its third such mission and fourth test overall - before it routinely carries US astronauts.
Boeing, which congratulated the astronauts' return on X, did not respond immediately to a request for comment.
286 DAYS IN SPACE
The ISS, about 254 miles in altitude, is a football field-sized research lab that has been housed continuously by international crews of astronauts for nearly 25 years, a key platform of science diplomacy managed primarily by the US and Russia.
Swept up in NASA's routine astronaut rotation schedule, Wilmore and Williams worked on roughly 150 science experiments aboard the station until their replacement crew launched last week.
The pair logged 286 days in space on the mission - longer than the average six-month ISS mission length, but far short of US record holder Frank Rubio, whose 371 days in space ending in 2023 were the unexpected result of a coolant leak on a Russian spacecraft.
Living in space for months can affect the human body in multiple ways, from muscle atrophy to possible vision impairment.
Williams, capping her third spaceflight, has tallied 608 cumulative days in space, the second most for any US astronaut after Peggy Whitson's 675 days. Russian cosmonaut Oleg Kononenko set the world record last year at 878 cumulative days.
"We came prepared to stay long, even though we planned to stay short," Wilmore told reporters from space earlier this month.
"That's what your nation's human spaceflight program's all about," he said. "Planning for unknown, unexpected contingencies. And we did that."
